1,347,794. Application filed November 28, 1917,

To all whom it may concern:

'Be it known that 1, CHARLES W. SAAL- BURG, of New York, in the count of New York and in the State of New ork, have invented a certain new and useful Improve ment in Plate-Holders for Making Changeable Pictures, and do hereby declare that the following is a full, clear, and exact desciiiption thereof..-

y invention relates particularly to an apparatus to be used for taking pictures adapted to change or give the effect of motion when viewed at different angles.

The object of my invention is to provide a camera of the above type which will 'permit the taking of composite pictures com-' prising a plurality of different pictures arranged in alternating lines, and which are very exactly placed in regard to one another, so as to obtain very accurately and completely the change from one picture to another when the composite picture is viewed from different angles. The object of my invention is particularly to provide an apparatus of this character which will enable pictures of "large size to be taken while the different pictures comprised'inthe I composite picture will occupy very exactly their different positions, and in such away that the lines in the said pictures are in exactly parallel positions. Another object of my invention is to provide a shifting mechanism for the screen in the camera which is protected from displacement between the operations thereof. Further objects of my invention will appear from the detailed description of the same contained hereinafter.

While my invention is capable of embodi-- ment in many different forms, for the purpose of-illustration I have shown only one form thereof in the accompanying drawings,

'in which,

Fig. 2 is a vertical section line 27-2. 9

In the drawings of the same on I have shown a plateholding apparatus 7 which may be mounted in any suitable manner on a camera (not shown)- The apparatus 7 comprlses an outer frame 8 having-within the 'same'and near the front thereof,:a-thinframe; Q-provided-J Specification of Letters Patent...

with an opening 10 to admit light. In the rear of said frame 9 there are a v.pair of guides 11 carried upon the frame 9 to receive sliding bars 12 and 13 connected .to a frame 14 carrying a screen 15 made of a sheet ofv glass and having a pluralityof ver- I I ticalopaque lines 16. he sliding bars 12 and 13 are connected at their other ends to links 17 and 18 respectively, and said'links 17 and-18 are connected at their remaining ends to a sliding bar 19 carried in guides 20 and 21 also on the frame 9. In the center of the rod 19 there is an annular recess. 22 to receive a rotary stop 23 having a handle 24. The stop 23 is normally pressed by means of a spring 25 against the plate 26 on the frame 9, said plate carrying two pairs of lugs 27 and 28 to position the stop 23. The frame 14 has beveled ed es 29 to fit within correspondinglyshape recesses 30 in a stationary frame 31 attached to an inner frame 32 adjacent to theframe 9.

The stationary frame 31 is, furthermore,

provided with a recess 33 to receive a sensitive plate, 34 which is maintained securely in position by means of a spring 35 secured Upon the rear of the outer by hinges 37. Said cover has upon its inner face a forwardly projecting ridge 38 to fit around the frame 30 so as to prevent access of light to the plate 34. Pivoted catches 39 cooperate. with angle bars 40 on the frame-8 to hold the cover 36 in place. "Attached to the free edge of the cover 36 there is a movable portion 41 carried upon hinges -42'andwhich is provided with pivoted catches43' to engage front of the frame 9 there is, furthermore, provided a'three-sided bracket 44 to receive a shutter 45 whichfrnay be pulled out to expose the plate 33in the camera.

withangle bars 44 onthe frame 8. -Upon the In the operation of my invention, when it v is desired to take'a'comp'osite: 'icture the plate-holding device7 is iriserte in the recess 6 and the camera is focusedfinthe usual way. Thereupon an exposure' of the plate 34 is made with the screen 15' inone position v as shown in Fig. I p v v 23 is then shifiedto the 1. After this exposure has pictures located in alternating lines thereon.

These two pictures may be of two different subjects or they may be two positions of a moving object. From this negative suitable positives may be made. The movement of the screen 15 by this mechanism insures the maintenance of the upper and lower portions of the screen 15 in the same relative positions in the different positions of said screen. In other words, in the two positions of the screen, the lines 16 therein will be exactly parallel to one another and in this way the composite picture will be very accurately taken. This is important as the lines in the screens are often very fine and very close together and an inaccuracy in their location will be apparent in the pictures produced thereby. When viewed the whole of one of the pictures will be visible while the other picture will be entirely out off from view. Furthermore, while the pictures are being taken there is no danger of the incidental displacement of the screen positioning mechanism, as it 'is located inside of the frame. However, when the shifting mechanism is-being operated light is excluded from the sensitive plate.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit of my invention.
